The noise of a jet engine has nothing to do with mechanical vibration of the engine so you cannot simply try to equate rpm to Hz. The noise is made by oscillations in the airflows. Have you never...

MEMS gyros are prone to interference from ultrasonic sound at the high frequencies at which the gyros vibrate. It is a well known phenomenon. Totally unrelated to piston engine airframe vibration...

I have just had a play with the Assist, it is clever enough to recognise the difference between aileron control and flaperon control, so even at 100% flaperon travel it does not apply the stick...

As much as possible, you should only use the double sided tape to mount a gyro. This is in the instructions of every brand of gyro, not just Assist. Do not use hard mounts, clips, velcro straps...

Sadly, the Assist gyro is getting a lot of reports of acoustic interference from jet engines. You should ground test it before flying. With the engine running, switch the gyro on, turn up the gain,...

If you have created a steering function then it has all the software it needs to control it. Mixing rudder to it is unnecessary and is a hangover from the JR/Futaba way of thinking.

I recommend that you do not use the Tx Gyro function with Assist. The gyro functions were not designed for Assist and need to be re-written by Jeti to work properly with Assist. The gyro function...

No, it was bad because it was too responsive. Jeti was badly advised and they made the Assist into a flight controller, not a traditional gyro. It took over the controls and moved the surfaces far...

A gyro does not care where it is placed in a rigid body. However, an accelerometer does care, and the Assist uses both. Hence Jeti's instruction to mount the Assist near the CG. We don't know what...

I did look at playlists, but got the impression they were personal to each user and not something that could be published. Is that not right then?
